PermissionsHelper

Utility object for checking Bluetooth Low Energy (BLE) related permissions.

This helper simplifies the complexity of BLE permission handling across different Android versions. Starting from Android 12 (API 31, codename "S"), new granular Bluetooth permissions were introduced:

• Manifest.permission.BLUETOOTH_SCAN - Required for scanning BLE devices

• Manifest.permission.BLUETOOTH_CONNECT - Required for connecting to BLE devices

• Manifest.permission.BLUETOOTH_ADVERTISE - Required for advertising as a BLE peripheral

On older Android versions (below API 31), Manifest.permission.ACCESS_FINE_LOCATION is typically required for BLE scanning operations.

Usage Example

if (PermissionsHelper.hasScanPermissions(context)) {
    // Safe to start BLE scanning
    bleScanner.startScan()
} else {
    // Request BLUETOOTH_SCAN or ACCESS_FINE_LOCATION permission
}
